Development of improved preventative therapeutic strategies for the control of infectious disease [ 2007 - 2013 ]

Research Grant

Researchers: Prof James Paton (Principal investigator)

Brief description A major objective of this Australia Fellowship application is to provide a mechanism whereby, for the first time in my career, I can devote myself full-time to my program of research. This program addresses an issue of global significance, namely the control of bacterial infectious diseases. These continue to cause massive global morbidity and mortality and constitute a profound threat to human health, in spite of the availability of antimicrobial drugs for over 60 years. WHO estimates that bacterial infections are responsible for >10 million deaths p.a., and the economic impact is inestimable. For most major pathogens, vaccines are either unavailable or have serious shortcomings. Resistance to commonly used antimicrobials is increasing at an alarming rate, and modern travel has assisted the rapid global dissemination of highly resistant and virulent clones. Morbidity and mortality are also predicted to increase as a consequence of human-induced environmental changes and the growing proportion of the population with increased susceptibility to infection. Effective management of bacterial infectious diseases in the 21st century will require a two-pronged approach involving the development of cheaper and more effective vaccines, as well as novel anti-infectives refractory to known resistance mechanisms. However, formulation of optimal therapeutic and preventative strategies demands a thorough understanding of the biology of disease, particularly the complex interactions between bacterial pathogens and their human hosts. I have also played a leadership role in establishing the Pneumococcal Vaccine Consortium, which has just submitted a co-ordinated suite of multicentre proposals to PATH Vaccine Solutions to fund final preclinical testing, GMP scale-up and Phase I-II-III trials of protein-based pneumococcal vaccines that we have developed. The PATH accelerated pneumococcal vaccine development program is of enormous potential significance, because there is now a very real probability of pneumococcal protein vaccines being fast-tracked into human trials. Our aim is to create a direct pipeline from antigen discovery in the collaborators’ laboratories into the clinic. If successful, these vaccines could save millions of lives. This will be of enormous satisfaction to me personally, as it was I who originally proposed and demonstrated “proof of principle” for the vaccine potential of pneumococcal proteins, and I have been advocating assessment of their protective efficacy in humans for over 20 years. Thus, receipt of an Australia Fellowship will undoubtedly further support the internationalisation of Australian medical research.
